I have a buddy who tossed his macbook on his bed and it slid right off and damaged the LCD screen. I decided to take the challenge and just buy another LCD panel and repair it myself. I purchased another LCD panel and using the guides over at ifixit.com I installed it. I booted up the macbook to find that there was no back lighting but I could seen the screen displaying an image. After doing some searching I found the the inverter was the most likely problem and promptly ordered another. Today I installed the new inverter to find the same problem. No back lighting..... I have double checked both the inverter cable connection and the optical connection. Would anyone have any other ideas at this point? Any help is appreciated.
